Ender 3 v2 Gaps in print

[grahamdw]

HelloMy ender 3 v2 worked perfectly. then i packed it away and took it on a plane back to the UK now all my prints have weird gaps in them. Please see the attached image.It is not the gcode as it is the same gcode as i was using before the move. This tells me it is something to do with the printer itself. Maybe something that got damaged on the flight.I have tried cleaning then replacing the nozzle. adjusting the belt tensions. even tried upgrading the firmware (although it worked fine before).Any ideas before i start spending money replacing parts? at least which part may be to blame.
